TIE-GAR FOR IMPREGNATING-TANKS.

Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed May 22,1907. Serial No. 375,170-

To all whom it may concern:

Be it known that THOMAS H. Sues, a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, hasinvented certain new and useful Improvements in Tie-Cars forImpregnating- Tanks, of which the following is a specification.

My invention relates to improvements in tie cars for impregnating tanks,and relates especially to an improved form of side sill therefor, and toprovide a bracing construction of said side sill in conjunction with theend sill of said car.

In cars of this nature hitherto, it has been usual to connect the endsills and side sills and to strengthen the junction of the same withgusset plates riveted at the angle of the union of the two sills; thisinvolves a great deal of material and much labor in the construction,and adds materially to the weight of the car, as well as to its cost.

My improvement which will be hereinafter described obviates the use ofgusset plates, and hence reduces the time and labor of construction andthe cost thereof and produces a car which is of any desired strength.

In the drawings, Figure 1 is a perspective view of the car in place in atank, the latter being broken away; Fig. 2, is an end view of the carpartly in section; Fig. 3 is a side view of the car with a part brokenaway; Fig. 4 is a transverse section through the end sill showing theside sill in place thereon.

Referring to the drawings, 1 indicates a tank, in which are positionedthe rails 2 and 3, upon which the car isadapted to move; 4 representsthe trucks of the car, with the cross bracing construction 5, the sidesills being shown at 6 and 7. These side sills are pressed into shape,and extend from one end of the car to the other, and rest upon thetrucks. They act as a cover for the wheels, and as seen are composed ofthe flange portions 8 and 9 and the upwardly extending cover portion 10,thereby forming an inverted U. This pressed shape has great power ofresistance as well as comparative lightness; near the ends of the flangeportions 8 and 9 are buckled or crimped portions as shown at 11 for thepurpose now to be described.

The end sill 12 extends across the car in a horizontal plane and at eachside thereof curves upwardly and outwaidly as shown at 13 and 14. Theend sill is secured to the side sills by rivets or bolts 15, and has achannel 16 formed therein beginning near one end thereof and terminatingadjacent the other end thereof. This construction of the end sillprovides a channel which has a groove formed on the outer face thereof,as appears in Fig. 4. Into this groove the-fold or crimped portion 11 ofthe flanges of the side sill enter, and when the sills are securedtogether, a firm bracing construction is provided. Any tendency of theend sill to be twisted from position will be checked by the bracingconstruction formed by the engagement of the fold 11 with the groove 16,and it is apparent that the side sill is strengthened and maintained inproper position by the same engagement. Therefore a mutually bracingconstruction is provided by the formation of the folds on the flanges ofthe side sills and their positioning in the groove formed in the upperface of the end sills or channels. The end sill or bolster, as it issometimes called, is shown in elevation and also in transverse sectionin Fig. 3, and it may be seen in longitudinal sec tion in Fig. 2. Whenthe ties are placed on the car, they are maintained in position thereonby the bail 17, which is preferably secured adjacent the upper ends ofthe bolster.

The car thus formed is very simple in its construction and very strong;pressed shapes are utilized for forming both the side sills and the endsills, and the formation of the groove in the end sill and the dependingloop or buckle in the side sill to engage said groove on both sides ofsaid sill and at both ends thereof, renders the car capable ofsustaining a heavy load and also maintains the same against any tendencyto twisting or loosening of parts. Further, the weight and cost of thecar are materially reduced, and the wheels are completelycovered;loading of the car may be carried on without wasting time toarrange the ties with reference to the wheels, for the side sillcompletely prevents any contact of the ties with the wheels. Thereforethe free movement of the car is never hindered by the ties rubbingagainst the wheels and locking the same.

I claim:

1. In car for wood impregnating tanks, a side sill formed of a pressedshape and adapted to cover the wheels of the car, an end sill, and foldsformed on said side sill adapted to engage said end sill for bracing thesame.

2. In a car for wood impregnating tanks, a side sill formed of a pressedshape and adapted to form a cover for the wheels on one side of the car,an end sill formed of a pressed shape and secured to said side sills,flanges on said side sills having folds therein, and a groove formed onsaid end sill with which said folds are adapted to engage, therebyforming a bracing construction.

3. In a car for Wood impregnating tanks, an integral side sill pressedinto shape having side flanges, folds formed in said side flangesadjacent the ends thereof, an end sill pressed into channel shape andhaving a longitudinal groove on its upper face which said folds areadapted to enter, means securing said end sill and side sill together,said side sill being formed to cover the wheels on said car.

4. In a car for wood impregnating tanks, :1 side sill formed of apressed shape, an end sill. a corrugation formed on said side silladapted to engage said end sill, thereby forming a bracing construction.

In testimony whereof I aflix my signature in the pres ence of twowitnesses.
